03 Ford F250 5.4 Hesitates when accelerating at high speeds

Asked by Chiefsforever46 Dec 20, 2018 at 10:28 AM about the 2003 Ford F-250 Super Duty XLT Crew Cab RWD

Question type: Maintenance & Repair

My 5.4 F250 runs well except intermittently it will
hesitate when stepping on the gas at high speeds.  
It acts like I didn't step on the pedal then in 4-6
seconds it'll gun it and be fine. I ran some sea
foam spray through it but it didn't help any that I
could tell. I also manually cleaned the throttle
body.  Any ideas?
